  • the end 25 of the cleaning article 20 that is opposite the opening 24 (that is, the portion within which the user's finger tips will lie), will be referred to as the "opposing end”.
  • the opposing end 25 forms a closed structure to cover the user's fingers.
  • the opposing end 25 is also rounded (or convex) when the article is seen in a plan view from one of the faces of the same.
  • the body portion 22 has a longitudinal centerline L and a transverse centerline T, and comprises a first side (or "first face") 26, and a second side (or “second face”) 28.

  • the webs 31 have transverse slits 33 in their longitudinal side edges to form the strips 30.
  • the strips 30 are formed between each pair of slits 33.

  • Each strip 30 has two ends, a proximal end 30A, and a distal end 30B.
  • the strips 30 are joined to the body portion 22 at their proximal ends 30A by bonds 32.
  • the strips 30 can be joined to the body portion 22 so that the distal ends 3OB of the strips 30 in adjacent columns, C, overlap.
  • the strips 30 can be configured to overlap when the strips 30 are in a flattened condition (that is, when they are not fluffed) and/or in a fluffed condition.
  • joind encompasses configurations in which an element is directly secured to another element by affixing the element directly to the other element; configurations in which the element is indirectly secured to the other element by affixing the element to intermediate member(s) which in turn are affixed to the other element; and configurations in which one element is integral with another element, i.e., one element is essentially part of the other element.

  • topsheet 46 One suitable apertured formed film topsheet for the topsheet 46 is the formed film described in one or more of the above patents and marketed on sanitary napkins by The Procter & Gamble Company of Cincinnati, Ohio as the "DRI-WEAVE" topsheet.
  • apertured spunlace materials can be obtained from BBA Nonwovens.
  • the apertured topsheet 46 can comprise any suitable nonwoven material.
  • the apertured topsheet 46 comprises a stretch apertured nonwoven material.
  • the apertures 56 of the stretch apertured nonwoven material are arranged in diagonal rows.
  • the apertures 56 of this particular nonwoven may also be thought of as being arranged in a hexagonal repeating pattern. In this pattern, the sides of the repeating units of which are formed by six apertures, and there is one aperture in the center of each repeating unit.
  • This apertured nonwoven material has portions of the surface of the same (the unapertured portions) that have dimensions between the apertures 56 that are at least about one-half the width of the apertures 56.
  • the unapertured portions can range in size up to the size of the width of the apertures 56, or greater. In some embodiments, this may be useful to obscure the secondary component from view better than if the cleaning surface was formed by a scrim with openings that are larger than the structural elements comprising the scrim.
  • Suitable stretch apertured nonwoven materials are described in U.S. Patents 5,628,097; 5,658,639; and 5,916,661.
  • Apertured nonwoven materials may also be distinguished from scrim materials in several other respects. While scrims also have apertures, scrims are often formed from continuous length intersecting structural elements that have circular cross-sections. The structural elements of scrims will often form raised nodes where they intersect and are welded together, while nonwoven materials often have structural elements that intersect, but at less pronounced, generally planar points of intersection. It is believed that, in some cases, the nodes of some scrim materials can scratch some surfaces, such as the surfaces of a vehicle. Also, scrims may tend to have too high of an open area, thereby allowing soil to easily come into contact with the surface of the vehicle.
  • the apertured topsheet 46 can have any suitable amount of open area.
  • the apertured topsheet 46 may have between about 20 and about 80% open area, alternatively between about 30 and about 70% open area, or alternatively, between about 40 and about 60% open area.
  • the apertures may permit water (and/or a cleaning composition) and/or soil particles to pass through their openings and into the underlying secondary component material directly beneath, thereby preventing direct interaction between these soil particles and the surface of the vehicle.
  • Suitable underlying materials that can be used in combination with an apertured topsheet 46 include, but are not limited to, high loft nonwoven polymeric battings having a basis weight of 40 grams/m 2 (gsm) and above. Such materials are available from Polymer Group Incorporated ("PGI") of Mooresville, NC, U.S.A. In one embodiment, a 75 grams/m 2 polypropylene, polyester, PE/PP biconiponent fiber nonwoven batting from PGI that is made by carding and then through air bonded can be used.
  • the secondary component 48 which is best seen in FIG. 12, is positioned between the topsheet 46 and the backing layer 54.
  • the secondary component may, but need not, serve one or more of the following functions: a cushioning function; a spacing function; an absorbent function; a soil capturing function; and/or a lathering function for lathering a cleaning composition.
  • the secondary component 48 may be generally compressible, and conformable.
  • the secondary component 48 may, in some embodiments, be capable of absorbing and/or retaining liquids. In other embodiments, the secondary component 48 need not be capable of absorbing and/or retaining liquids.
  • the secondary component 48 may be manufactured from a wide variety of materials, including those commonly used in absorbent articles. Suitable absorbent materials comminuted wood pulp which is generally referred to as airfelt.
  • absorbent materials examples include cotton fibers or cotton lintels, creped cellulose wadding; meltblown polymers including coform; chemically stiffened, modified or cross-linked cellulosic fibers; synthetic fibers such as crimped polyester fibers; peat moss; tissue including tissue wraps and tissue laminates; absorbent foams; absorbent sponges; superabsorbent polymers (in fibrous and particulate form); absorbent gelling materials; or any equivalent material or combinations of materials, or mixtures of these.
